It's a while since I messed with these type of carb, but I thought the
purpose of the damper was to keep the mixture nice and rich for a few
moments when you pressed the loud pedal. BICBVW.

I think that is the case, in which thicker oil will cause the damper to act
slower therefore keeping it richer slightly longer. I seem to recall over
the years different oil was specified, from something as thin as 3 in 1 type
to ATF to 20/50. I also read thicker oil is more suitable for (a) a worn
carb and (b) lower rpm.
In my 90 V8 (SU's) I use GTX which seems to work ok.
